<u>Chemical</u>. The copper atoms form new chemical bonds with atoms in the air.
When the seasons change from winter to spring, the wolves inner layer of fur, which traps air and insulates the wolf from harsh cold temperatures, is shed to keep the wolf cool when the heat starts to come back.
Answer: If the intermolecular forces are weak, then molecules can break out of the solid or liquid more easily into the gas phase. Consider two different liquids, one polar one not, contained in two separate boxes. We would expect the molecules to more easily break away from the bulk for the non-polar case. If the molecules are held tightly together by strong intermolecular forces, few of the molecules will have enough kinetic energy to separate from each other. They will stay in the liquid phase, and the rate of evaporation will be low. ... They will escape from the liquid phase, and the rate of evaporation will be high. To make water evaporate, energy has to be added. The water molecules in the water absorb that energy individually. Due to this absorption of energy the hydrogen bonds connecting water molecules to one another will break.
Hope this helps..... Stay safe and have a Merry Christmas!!!!!!!! :D
